Set selected row index in DevExpress Grid Control by C# code

In DevExpress grid control there is no direct property to set selected row index from C# code if you need to do so. To achieve this functionality one needs to define TableView for the DevExpress grid control. The TableView is defined under <dxg:GridControl.View></dxg:GridControl.View> tag.

To add DevExpress Grid you will require
xmlns:dxg='http://schemas.devexpress.com/winfx/2008/xaml/grid'

In the TableView there is a property called "FocusedRowHandle" which is used to set the selected row index in the GridControl

Consider Sample XAML Written Below

<StackPanel>
   <dxg:GridControl Height='300' Grid.Column='0' Grid.Row='1' x:Name='grdDetail'         IsFilterEnabled='False' IsManipulationEnabled='False'>
   <dxg:GridControl.Columns>
         <dxg:GridColumn Header='SeqNo' AllowResizing='False' Width='30' 
          FieldName='[SeqNo]' HorizontalHeaderContentAlignment='Center'
          AllowSorting='False'>
              <dxg:GridColumn.CellTemplate>
                  <DataTemplate>
                    <TextBlock HorizontalAlignment='Left' VerticalAlignment='Center' 
                    Text='{Binding Path=RowData.Row.[SeqNo]}'></TextBlock>
                  </DataTemplate>
              </dxg:GridColumn.CellTemplate>                    
         </dxg:GridColumn>
         <dxg:GridColumn Header='RollNo' FieldName='[RollNo]' AllowSorting='False'>
              <dxg:GridColumn.CellTemplate>
                  <DataTemplate>
                   <TextBlock HorizontalAlignment='Right' VerticalAlignment='Center' 
                    Text='{Binding Path=RowData.Row.[RollNo]}'></TextBlock>
                  </DataTemplate>
              </dxg:GridColumn.CellTemplate>
         </dxg:GridColumn>
         <dxg:GridColumn Header='Name' FieldName='[Name]' AllowSorting='False'>
              <dxg:GridColumn.CellTemplate>

                  <DataTemplate>
                   <TextBlock HorizontalAlignment='Center' VerticalAlignment='Center'                     Text='{Binding Path=RowData.Row.[Name]}'></TextBlock>
                  </DataTemplate>
              </dxg:GridColumn.CellTemplate>
         </dxg:GridColumn>
         <dxg:GridColumn Header='Marks' FieldName='[Marks]' Width='50' 
           HorizontalHeaderContentAlignment='Center' AllowSorting='False'>
               <dxg:GridColumn.CellTemplate>
                  <DataTemplate>
                   <TextBlock HorizontalAlignment='Right' VerticalAlignment='Center' 
                    Text='{Binding Path=RowData.Row.[Marks]}'></TextBlock>
                  </DataTemplate>
               </dxg:GridColumn.CellTemplate>
         </dxg:GridColumn>
         <dxg:GridColumn Header='Rank' FieldName='[Rank]' Width='50' 
           HorizontalHeaderContentAlignment='Center' AllowSorting='False'>
               <dxg:GridColumn.CellTemplate>
                  <DataTemplate>
                    <TextBlock HorizontalAlignment='Right' VerticalAlignment='Center' 
                     Text='{Binding Path=RowData.Row.[Rank]}'></TextBlock>
                  </DataTemplate>
               </dxg:GridColumn.CellTemplate>
         </dxg:GridColumn>
       </dxg:GridControl.Columns>
       <dxg:GridControl.View>
         <dxg:TableView Name='tblViewDetail' AllowColumnFiltering='False' 
          AllowEditing='False' AllowGrouping='True' AllowResizing='True'  AllowSorting='True' AutoWidth='True' ShowGroupPanel='False' 
          ShowIndicator='False' ShowVerticalLines='False'>
         </dxg:TableView>
       </dxg:GridControl.View>
   </dxg:GridControl>
   <StackPanel Orientation="Horizontal">
       <Button Content="Select 1st Row" Click="Button_Click" x:Name="Sel1"></Button>
       <Button Content="Select 2nd Row" x:Name="Sel2" Click="Sel2_Click"></Button>
       <Button Content="Select 3rd Row"  x:Name="Sel3" Click="Sel3_Click"></Button>
   </StackPanel>
</StackPanel>

Now In this XAML we will add ItemSources by C# Code as well as selected row will be set by c# code. The C# Code will be as followed



C# Code

public partial class MainWindow : Window
{
  DataTable dt;
  public MainWindow()
  {  
    InitializeComponent();
    dt = new DataTable();
LoadTable();
grdDetail.ItemsSource = dt;
  }


  public void LoadTable()
{
dt.Columns.Add("SeqNo");
dt.Columns.Add("RollNo");
dt.Columns.Add("Name");
dt.Columns.Add("Marks");
dt.Columns.Add("Rank");
     DataRow dr = dt.NewRow();
dr["SeqNo"] = "1";
    dr["RollNo"]= "789159";
dr["Name"] = "Adam";
dr["Marks"] = "785";
dr["Rank"] = "6";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["SeqNo"] = "2";
dr["RollNo"] = "789209";
dr["Name"] = "Shaun";
dr["Marks"] = "845";
dr["Rank"] = "2";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["SeqNo"] = "3";
dr["RollNo"] = "789205";
dr["Name"] = "Shane";
    dr["Marks"] = "844";
dr["Rank"] = "3";
dt.Rows.Add(dr);
  }
  private void Button_Click(object sender, RoutedEventArgs e)
    {
      tblViewDetail.FocusedRowHandle = 0; //Selecting 1st Row
    }
  private void Sel2_Click(object sender, RoutedEventArgs e)
    {
      tblViewDetail.FocusedRowHandle = 1; //Selecting 2nd Row
    }
  private void Sel3_Click(object sender, RoutedEventArgs e)
   {
      tblViewDetail.FocusedRowHandle= 2; //Selecting 3rd Row
  }
}

Output
